Sishen Pills is a classic prescription for the treatment of spleen and kidney diarrhea,which has the effect of warming the kidney and the spleen,astringent intestine and antidiarrheal.In modern clinical application,the modified prescriptions based on Sishen Pills,combined with other treatments of TCM and integrated traditional Chinese and Western medicine are often used to treat ulcerative colitis with spleen-kidney yang deficiency syndrome,and the curative effect is remarkable.Experimental pharmacological studies have shown that Sishen Pills may achieve the purpose of ulcerative colitis by regulating the expression of related signaling pathway proteins,regulating inflammatory factors,inhibiting inflammatory response,regulating autophagy,regulating intestinal flora,improving intestinal mucosal permeability,repairing intestinal mucosal barrier,regulating cellular energy metabolism,anti-oxidative stress,regulating cellular immune function,etc.In this article,the research status of Sishen Pills in the treatment of ulcerative colitis was sorted out and summarized,in order to provide reference for further study of its mechanism and clinical application.

Objective: To investigate the correlations among striatal dopamine transporter (DAT) distribution, glucose metabolism and Parkinson′s disease (PD) clinical symptoms. Methods: Twenty-five clinically confirmed idiopathic PD patients (17 males, 8 females, age: (59.8±9.2) years) who underwent ¹¹C-2-beta-carbomethoxy-3-beta-(4-fluorophenyl)tropane (CFT) and ¹⁸F-fluorodeoxyglucose (FDG) PET imaging from January 2015 to December 2016 were reviewed. The detailed clinical scores were systematically collected from all patients. Correlations between DAT distribution, glucose metabolism and clinical symptoms were evaluated at global and voxel levels using Pearson correlation analysis. Results: There were significantly positive correlations between the PD-related pattern (PDRP) value and unified PD rating scale (UPDRS) motor scores, non-motor symptoms scale (NMSS) scores, activity of daily living scale (ADL) scores (r values: 0.580, 0.522, 0.557, all P<0.05). The CFT uptake of ipsilateral caudate nucleus, anterior putamen, and posterior putamen were negatively correlated with UPDRS motor scores (r values: -0.496, -0.492, -0.457, all P<0.05), while those had no significant correlations with NMSS scores (r values: -0.420, -0.402, -0.355, all P>0.05). The CFT uptake of ipsilateral caudate nucleus and anterior putamen were negatively correlated with ADL scores (r values: -0.502, -0.522, both P<0.05). There were no significant correlations between CFT uptake in contralateral striatal, anterior putamen, posterior putamen and PDRP values, UPDRS motor scores, NMSS scores and ADL scores(r values: from -0.466 to -0.129, all P>0.05). The presence of the significant correlations between UPDRS motor scores, ADL scores and the CFT radioactive count were confirmed in left caudate nucleus and left putamen (r values: from -0.90 to -0.47, all P<0.05). The metabolic PET imaging disclosed a set of brain regions correlating with the clinical symptoms. The presence of significant correlations between the metabolic PET imaging and CFT uptake were confirmed in bilateral caudate nucleus (r values: 0.47-0.90, both P<0.01), precentral gyrus and insula (r values: -0.90 to -0.47, all P<0.01). Conclusion The correlations between DAT distribution, glucose metabolism and PD clinical symptoms are complicated, which promote the understanding in the proper application of dopaminergic and metabolic PET imaging in PD and offer more evidences in PD pathophysiological mechanisms.
